Reaction Steps
To a solution of 2-chloro-1-(4-[[5-(trifluoromethyl)-1-benzofuran-2-yl]methyl]piperazin-1-yl)ethan-1-one (100 mg, 0.28 mmol) in acetonitrile (10 ml) was added potassium carbonate (57.5 mg, 0.42 mmol) and 4-[4-nitro-3-(trifluoromethyl)phenyl]aminophenol (83 mg, 0.28 mmol). The mixture was stirred and heated at 80° C. (oil bath) for 3 hours. The solids were filtered off and the filtrate was concentrated under vacuum to give a residue, which was purified by Prep-TLC with 60% ethyl acetate in petroleum ether to afford 2-(4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]phenoxy)-1-(4-[[5-(trifluoromethyl)-1-benzofuran-2-yl]methyl]piperazin-1-yl)ethan-1-one as a yellow solid (125.8 mg, 73%); (ES, m/z): [M+H]+ 623.20; 1H NMR (400 MHz, CDCl3): δ 8.00 (d, J=8.8 Hz, 1H), 7.86 (s, 1H), 7.60 (m, 2H), 7.14 (overlapping s & d, 3H), 7.00 (d, J=8.4 Hz, 2H), 6.92 (d, J=8.8 Hz, 1H), 6.72 (s, 1H), 6.29 (s, 1H), 4.74 (s, 2H), 3.91-3.53 (m, 6H), 2.60 (br s, 4H).
